Fibula Mass; Unusual Presentation of Stress Fracture with Pseudarthrosis: A Case Report

Stress fracture is a common diagnosis of pain in the lower extremity in the lack of obvious trauma history. Nowadays, with better recognition of its pathophysiology and advanced diagnostic facilities, it is more convenient to distinguish stress fracture. But in some cases, it is troublesome to differentiate stress fracture from serious conditions such as neoplasm. The current case report described an unusual case of proximal fibula stress fracture presenting with mass and local tenderness without history of trauma or vigorous activity.
